Full Description

OUTLINE: This is a multi-center study.

Eligible subjects must have received initial cisplatin-based combination therapy, such as bleomycin-etoposide-cisplatin (BEP), cisplatin-etoposide (EP), etoposide-ifosfamide-cisplatin (VIP), or similar regimens AND demonstrated progression following the administration of at least one 'salvage' regimen for advanced germ cell neoplasm, such as high dose chemotherapy, paclitaxel-ifosfamide-cisplatin (TIP), or vinblastine-ifosfamide-cisplatin (VeIP).

INVESTIGATIONAL TREATMENT:

Pembrolizumab 200mg IV every 3 weeks until progression or toxicity. Treatment will continue for up to 52 weeks in the absence of prohibitive toxicities or disease progression.

The following screening labs to demonstrate adequate organ function must be performed within 10 days of treatment initiation:

Hematological:

Absolute neutrophil count (ANC) ≥1,500 /mcL
Platelets ≥100,000 / mcL
Hemoglobin ≥9 g/dL or ≥5.6 mmol/L without transfusion or hematopoietin (EPO) dependency (within 7 days of assessment)

Renal:

Serum creatinine ≤1.5 X upper limit of normal (ULN) OR
Measured or calculated creatinine clearance ≥60 mL/min for subject with creatinine levels >1.5 X institutional ULN
Glomerular filtration rate (GFR) can also be used in place of creatinine or creatinine clearance (CrCl)

Hepatic:

Serum total bilirubin ≤ 1.5 X ULN OR
Direct bilirubin ≤ ULN for subjects with total bilirubin levels > 1.5 ULN
AST (SGOT) and ALT (SGPT) ≤ 2.5 X ULN OR ≤ 5 X ULN for subjects with liver metastases
Albumin >2.5 mg/dL

Coagulation:

International Normalized Ratio (INR) or Prothrombin Time (PT) ≤1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
Activated Partial Thromboplastin Time (aPTT) ≤1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants

Eligibility Criteria

Inclusion Criteria:

Written informed consent and HIPAA authorization for release of personal health information. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
Age ≥ 18 years at the time of consent.
ECOG Performance Status of 0 or 1 within 14 days prior to registration for protocol therapy.
Subjects must have histological or serological proof of metastatic germ cell neoplasm (gonadal or extragonadal primary) with disease not amenable to cure with either surgery or chemotherapy. Subjects with seminoma and non-seminoma are eligible, as are women with ovarian GCTs.
Subjects must have evidence of recurrent or metastatic carcinoma by one or more of the following: the appearance of metastatic disease on chest x-ray or CT scan, or the appearance of rising tumor marker: AFP or beta-HCG. NOTE: If a rising tumor marker is the only evidence of progressive disease, at least 2 consecutive rising values at least one week apart are needed. Subjects with only evidence of disease as rising tumor marker AFP and beta-HCG will be provided alternate causes of increased serum levels of these markers are not present, such as cross reaction with luteinizing hormone (LH) (that can be tested if needed by testosterone suppression of LH), hepatitis, use of marijuana, or second primary tumor, etc.
Subjects must have received initial cisplatin based combination therapy, such as bleomycin-etoposide-cisplatin (BEP), cisplatin-etoposide (EP), etoposide-ifosfamide-cisplatin (VIP), or similar regimens AND demonstrated progression following the administration of at least one 'salvage' regimen for advanced germ cell neoplasm, such as high dose chemotherapy, paclitaxel-ifosfamide-cisplatin (TIP), or vinblastine-ifosfamide-cisplatin (VeIP).
"Failure" of prior therapy is defined as: a >25% increase in the products of perpendicular diameters of measurable tumor masses during prior therapy which are not amenable to surgical resection; the presence of new tumors which are not amenable to surgical resection; an increase in AFP or beta-hCG (two separate determinations at least one week apart are required if rising tumor markers are the only evidence of failure). NOTE: Subjects with clinically growing "teratoma" (normal declining tumor markers and radiographic or clinical progression) should be considered for surgery.
Subjects are eligible after first line platinum based chemotherapy if their disease has relapsed and they have Primary Mediastinal Non Seminomatous Germ Cell tumor (PMNSGCT) or late relapse (> 2 years) not amenable to surgical resection.
Subjects must be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion. Newly-obtained is defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on Day 1. Subjects for whom newly-obtained samples cannot be provided (e.g., inaccessible or subject safety concern) may submit an archived specimen only upon agreement from the sponsor investigator
Female subjects of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication . Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.
Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.
Measurable disease according to RECIST v1.1 obtained by imaging within 28 days prior to registration.

Exclusion Criteria:

Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment.
Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment.
Has a known history of active TB (Bacillus Tuberculosis)
Hypersensitivity to pembrolizumab or any of its excipients.
Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events (AE) due to agents administered more than 4 weeks earlier.
Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent. NOTE 1: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for the study. NOTE 2: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.
Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.
Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e,. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
Presence of interstitial lung disease or history of pneumonitis requiring treatment with corticosteroids.
Has an active infection requiring systemic therapy.
Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment.
Has received prior therapy with PD-1, PD-L1, or CTLA-4 inhibitors.
Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).
Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA [qualitative] is detected).
Has received a live vaccine within 30 days of planned start of study therapy. NOTE: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist®) are live attenuated vaccines, and are not allowed.
